There are four ways to find a ratio.
1 A dealer can normally tell from the vin number.
2 There are normally tags or labels on the axle that have part number, gear ratio, and fluid requirement
info.
3 You can count how many times you have to turn the driveshaft to get one complete turn of the tires.
4 You can divide the number of teeth on the ring gear and divide by number of teeth on the pinion.
Mine is 3:55
Same as the rear.
it will be the same as the rear diff
2.833 is the rear-end gear ratio
The rear end gear ratio on a 1980 Oldsmobile is 3.73, in the overdrive gear. The low gear ratio is 1.43.
Could be any of several. Check the little metal tag bolted to the diff. That truck also likely has a 8.8 rear, not a 9 inch. If the tag says "88" it's an 8.8. The gear ratio will be stamped with no punctuation, i.e. "327" would be a 3.27 gear.
The stock rear-end gear ratio for all US 240sx is 4.083
The tag on the cover, bolted to one of the 10 bolts on a 8.8 rear, should spell it out for you. My Mustang GT tag reads 3L08 88 4B07. The first three numbers on the tag tells me its a 3.08 gear ratio. Assuming you are referring to a F150 with a 8.8 rear, Ford used the 8.8 on a bunch of cars and trucks.
it has an 8.8 rear end with a 3.23 ratio.
3.70 on a 2.4 liter, 4 cyl engine, according to spec sheet on window.
If the front is 3.55, then the rear needs to be 3.55
The gear ratio was whatever the customer ordered back then, you could get anything from a 2.76 ratio to a 4.10 rear gear.
